A circadian arm implant?🤯 If this works, it's probably going to be useful for more than jetlag

THIS! Have a look at this funny and informative comic explaining what you need to know about light, our body-clocks, and sleep!

The #DaylightWeek is only one week away! The first session (25 May | 18:00 CEST) will be dedicated to the biological effects of #daylight. #Health benefits of #sunlight deserve to be more widely known. Spread the word and sign up now: bit.ly/32jlfTE #LightDay2021

Study testing multiple common sleep-tracking wearables: Most are OK at guessing if you're sleeping or awake, but not good for sleep stages. I think the larger question though, is whether there are any negative effects of getting your sleep evaluated each morning by your watch?

Today I had the honor or being a public opponent for an exciting PhD thesis on sleep and mild TBI. Congratulations to Simen Berg Saksvik and his mentor Alexander Olsen for an elegant body of work! Your findings will guide future studies on the consequences of sleep disturbances after TBI 🧠

Have to put up IKEA-furniture today. I am timing my effort to the afternoon/early evening where cognitive performance and alertness is higher. Also cranked up light levels in apartment to maximum - more alertness! No missing screw will stop me today! #circadian #IKEA

Hahaha I can often relate to this T-Rex

We need viable tools to help diagnose delayed sleep wake phase disorder (DSWPD) in the clinic. That's why I like this paper that uses bed/wake time and light info from an actiwatch to predict circadian phase. I could see this being used clinically doi.org/10.1038/s41598…

Yes! Finally someone got to testing a bunch of these commercially available blue-blocking glasses! So many to choose from, spoiler alert, not all of them are as blue blocking as they claim to be! tandfonline.com/doi/full/10.10…

hey #sleeptwitter! We are planning a short 10 min, children's (~10yrs) tv-programme about what happens in the brain during dreams. Meant to reduce anxiety about dreams and show how cool science is. Thoughts on what to include? The important bits for kids to know? (we have PSG)

Oh no! My oura ring is telling me I only got 4% deep sleep! What should I do? Nothing...other than ignore the sleep stage information. Sleep trackers are not accurate when it comes to sleep stages (see ref below). pubmed.ncbi.nlm.nih.gov/33378539/

At least the title of plastic surgeon finally makes more sense if we at some point need to remove the plastic in our bloodstream theguardian.com/environment/20…

How does insomnia develop? A nice video on how insomnia starts and the factors that keep it stuck. #insomnia #sleep #cantsleep SleepHub sleephub.com.au/how-does-insom…

As a clinician working daily with people with #insomnia, often driven by anxiety about #sleep, it’s disappointing when others in the sleep field overstate the impacts of sleep loss and fuel sleep-anxiety. Maintenance Phase maintenancephase.buzzsprout.com/1411126/9716285

hey #SleepPeeps! In our latest paper we found that evening blue-depleted lighting resulted in reduced REM sleep fragmentation and arousals. This seemed to be independent of the effects on circadian rhythms. No effect on REM-density. nature.com/articles/s4159…

looking forward to this.

Very proud to share this new pre-print which is the first to report the UK Biobank objective light data (in 85,000 people). We demonstrate robust associations of low daytime light and bright night light with a broad range of psychiatric disorders. medrxiv.org/content/10.110…

PhD-position alert! Our sleep research group in Norway is hiring 2 phd students for a project on machine learning and cognitive behavioural therapy for insomnia. We are a really nice bunch, and are excited to add new members. Please spread the word! jobbnorge.no/en/available-j…

I am now also on mastodon under @[email protected] I hope to see many of the academic twitter and sleep peeps over there.
